The net-reaction of all light-dependent reactions in oxygenic photosynthesis is: 2H 2 O + 2NADP+ + 3ADP + 3Pi → O 2 + 2NADPH + 3ATP Key Points Light energy splits water and extracts electrons in photosystem II (PSII); then electrons are moved from PSII to cytochrome b6f to photosystem I (PSI) and reduce in energy.
Jan 18, 2022 · In the light-dependent reaction, H + has an important part as a reminder to proceed with the reaction. Two stages carry out the process of photosynthesis. These are: Light-dependent reactions; Calvin cycle; Figure 4: Two stages of photosynthesis (Cikgurozaini, 2019). Notice the light reaction diagram (left) and the Calvin Cycle (right).
Sep 21, 2021 · Generating an Energy Carrier: ATP. In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.

The light reaction is also known as photolysis reaction and takes place in the presence of light. It usually takes place in the grana of chloroplasts. The photosystems have pigment molecules. In the plants, chlorophyll is one of the primary pigments which actively takes part in the process of light reactions like photosynthesis. The accessory pigme...
Light reaction is the first stage of photosynthesis processin which solar energy is converted into chemical energy in the form of ATP and NADPH. The protein complexes and the pigment molecules help in the production of NADPH and ATP. The process of light reaction is given below- 1. In light reactions, energy from the sunlight is absorbed by the pig...
The light reaction traps the energy from the sun and converts it into chemical energy that is stored in NADPH and ATP.Oxygen is released as the waste product.- 13 min
The reactions that make up the process of photosynthesis can be divided into light-dependent reactions, which take place in the thylakoids, and light-independent reactions (also known as dark reactions or the Calvin cycle), which take place in the stroma. 1. Chloroplasts have a complex internal structure, and different reactions take place in ...
Figure 25.3 25. 3: Photosynthesis takes place in two stages: light-dependent reactions and the light-independent reactions (Calvin cycle or Calvin-Benson cycle). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. In the process, water is used and oxygen is produced.

What is a light-dependent reaction?
In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom or group of atoms to the molecule. For ATP, it is a phosphate group, and for NADPH, it is a hydrogen atom.
